APPENDIX G
IDENTIFICATION ON SAILS

See rule 77.
G1 WORLD SAILING CLASS BOATS
G1.1 Identification
Every boat of a World Sailing Class shall carry on her mainsail and,
as provided in rules G1.3(d) and G1.3(e) for letters and numbers
only, on her spinnaker and headsail
(a) the insignia denoting her class;
(b) at all international events, except when the boats are provided
to all competitors, national letters denoting her national
authority from the table below. For the purposes of this rule,
international events are World Sailing events, world and
continental championships, and events described as
international events in their notices of race and sailing
instructions; and
(c) a sail number of no more than four digits allotted by her
national authority or, when so required by the class rules, by
the class association. The four-digit limitation does not apply to
classes whose World Sailing membership or recognition took
effect before 1 April 1997. Alternatively, if permitted in the
class rules, an owner may be allotted a personal sail number by
the relevant issuing authority, which may be used on all his
boats in that class.
Sails measured before 31 March 1999 shall comply with rule G1.1 or
with the rules applicable at the time of measurement.
Note: An up-to-date version of the table below is available on the
World Sailing website.
